Backstage: Improper input validation in Confluence to Markdown scaffolder module
### Impact Insufficient input validation in the Confluence to Markdown scaffolder module could allow an attacker to influence file write operations during template execution. Exploitation requires a Backstage user to run a template that processes attacker-influenced Confluence content. ### Patches Patched in `@backstage/plugin-scaffolder-backend-module-confluence-to-markdown` version `0.3.25` ### Workarounds If unable to update immediately: - Restrict Confluence edit access to trusted users. - Review Confluence page content before running scaffolder templates against untrusted pages.
